For large corporate clients (Orange, ICDC, France Travail, etc.), scale-ups, or startups, I have served as a Tech Lead on various projects with significant business stakes, strict performance constraints, and demanding SLAs, among other challenges. With a strong emphasis on sharing best practices and enhancing team expertise, I have guided numerous development teams of varying sizes (3 to 20 people). At the core of my approach lies the end-user experience. I am particularly attentive to security, privacy (GDPR), and performance aspects.
